Description

Technical Field

[0001] The invention relates to the technical field of water conservancy and hydropower engineering, and in particular to a conical dredging device and method for causing water flow to generate a wave flow state. Background Art

[0002] Most of my country's rivers have problems with silt sedimentation, riverbed rising and shallowing, and reduced water storage, water transmission and flood discharge capacity. Some sewage rivers are overflowing with sludge, polluting the environment, and require regular dredging.

[0003] At present, most of the conventional river dredging and desilting technologies are used in waterways and river sections with relatively small flow capacity. Common methods include building spur dikes to redirect water flow and local desilting and dredging operations by dredging ships. Spur dikes are divided into control-type spur dikes and control-type spur dikes according to their functions, and dredging ships are divided into grab-type dredging, pump-suction dredging, cutter-suction dredging and bucket-wheel dredging according to their dredging principles. Building spur dikes is more suitable for rivers with relatively stable river conditions and is applicable to limited scenarios. Although dredging ships can achieve dredging effects in a short time, the dredging effects are general, and the dredging process requires a lot of manpower, material resources and dredging machinery and equipment, which is costly. Summary of the invention

[0004] To solve the above problems, the purpose of the present invention is to provide a conical dredging device and method for causing water flow to produce a wavy flow state, which relies on the interaction between natural water flow and the conical dredging device to produce a wavy water flow state, so as to enhance the sand-carrying force and scouring force of the water flow beside the conical dredging device, so as to achieve the purpose of dredging and diverting the river.

[0005] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme:

[0007] Furthermore, at least one group of cross-shaped support rods is arranged in the cavity inside the above-mentioned main body, and both ends of the support rods are fixed on the inner wall of the side panel.

[0008] Furthermore, the bottom surface of the support plate is fixed with anti-slip studs evenly distributed in an array.

The lifting rings of the conical drainage devices can be used for lifting. At the same time, water is injected and drained from the cone cavity structure to achieve the descent and buoyancy of the cone in the water. When injecting water, the upper air vent is exhausted and water is injected through the lower water hole so that the cavity of the main body is filled with water, and the foundation support plate sinks on the designated river sediment. , anti-slip nails are inserted into the bottom mud to keep the position stable; when the water flows through the conical dredging device and the river beach that needs to be flushed, the wave bulges A and B on the conical dredging device cause the water flow in the interval to produce a wave flow state, and through the changes in the water cross-sectional area and the change in the water flow velocity, the sand-carrying force of the water flow in the interval is enhanced, so as to achieve the effect of flushing the corresponding river channel and beach; after use, compressed air is injected through the upper air vent, and the lower water hole is drained to discharge the water in the main body cavity, so that the conical dredging device floats, and the lifting equipment is used again to move and lift the conical dredging device out of the river channel.

The wave protrusion B also serves as a reinforcing rib. A lifting ring 9 is provided on the upper part of both ends of the base support plate. The surface of the side panel 3c is smooth and flat, and a vent hole 4 and a water hole 11 are respectively provided on the upper and lower parts of the surface. A positioning rod 2 is fixedly welded to the top of the main body, and a floating ball 1 that can slide up and down is mounted on the positioning rod.

[0024] The bottom panel 10 of the main body of the triangular pyramid structure is slightly higher than the bottom ends of the side panels 3a, 3b and 3c, that is, higher than the base support plate 7, so that when the riverbed is raised or there are stones, the conical dredging device can be placed horizontally and stably placed on the mud in the river channel through the anti-slip nails 8.

[0025] The surface of the floating ball 1 is coated with color, which makes it easier for the personnel involved in the river or reservoir where the conical dredging device is deployed to identify the position of the conical dredging device in the river.
